It'd be a fun project, not too difficult either. Plus I could make my own features based on what *I* want, not what someone else wants.Kooldino said:

That's the FIRST time I've seen an aftermarket turbo kit for an N/A protege run more HP than TQ.

And even Spool's old dynos on his site show more TQ than HP.

I think we are on the same track. Most of the software that comes with scan tools and engine management setups sucks. I am big into interface, and even AEM's standalone software blows. They made an attempt at "3D" map graphs, but failed miserably. If someone has writen drivers for an OBD-II -> serial or USB adapter, then making the software will be a snap. It would be a great open-source project and a lot of help to the forum. I think a lot of innocent FZ-DE's could be spared...

so does this tool allow you to get rid of a cel or jsut tell you why you threw a cel?
that would be a deciding factor for me.
that would be a deciding factor for me.
What I really want to know is that if I get an adapter and some drivers, can I reprogram the ignition and fuel maps? When I took my MSP in to get it flashed, they uploaded it through that OBD-II port (as far as I've heard). So what's stopping me from doing the same thing? I'm sure that everything is in a certain format, and may have encryption and/or security codes, but I doubt that it would be impossible to figure out a way around it.
From my programming and electronic experience, although I know absolutely nothing about the specifics of how the ECU works, I know that all it does is read, modify, and output voltage signals. The programming to tell it how and when to do that is more than likely stored in an EEPROM (since the dealer flashed mine), and even if it's secured, a daughter-board with it's own EEPROM could be attached downstream from the ECU to capture and further modify the voltages to the injectors, ignition, etc.
Oh, wait, that's called a piggyback...

One more thing to add:
I know that the Ford ECU in my Speed learns around the changes made by most piggybacks because of the sensor readings and such. Why doesn't someone make a piggyback that reads the sensors directly, then either feeds the stock ECU what it wants to see in order to not modify the maps, or a constant stream of fixed (false) readings so that it remains predictable. Then the piggyback would have a base reference from the stock ECU and could alter the signals freely without worrying about the stocker ECU catching on.
I don't really feel like searching down the piggyback thread and having this lost in it.

Or better yet, a reverse piggyback, which would take the stock signals from the ecu (generated by the stock sensors), and modified them on their way to the fuel injectors.
Too bad a standalone costs nearly a grand, and who knows if they have a base program for the FS-DE.

Yes, they allow you to clear codes. . .but unless you "fix" the problem or "fool" the ecu somehow, the code will just come back.
They are a great thing to have. Which one is the best? Hell I don't know. I thought my Auto-Tap would be the best for me, but I haven't played with the others. (I was disappointed in how little "info" I was able to get with the Auto-Tap, but I've only just begun to play with it, so maybe it is user error.)

The Scantool.net hardware's free software is ok for basic stuff. The software done by Digimoto (www.digimoto.com) works as well for it for $50 and has all the bells and whistles.

You talkin' to me?
I almost bought the Digimoto one before, but I bought the auto-tap so as to be able to work on other cars, but I think I got duped in that it doesn't seem to do as much as the digimoto. . .but I hadn't thought about buying their software. . .that is definitely an option.

you would need a standalone or piggyback - these devices just read signals.

actually just speaking in general
the scantool i bought though has been helpful so far on my protege5, my brother's neon and my friend's eclipse (all of them are the same protocol) even with the free software.Kool, so you went with the Auterra. I have the Nology PDA Dyno that I believe was based off the Auterra when it was free. Nology was a lot more expensive (over $300 for cable and software). Now Auterra is up to par, and a little cheaper. I've had the Nology port of the software over a year, and can tell you the same things Dana laid out in the 1st post. Here is my original thread on my experiences: http://www.msprotege.com/forum/showthread.php?t=12846

You need the $85 package (or the $110 package with the steel case for the circuit board)...not just the $25 cable.paulmp3 said:
Buy that, download the free software, and you're set.

the first combo is the one i need for my car.. right?
also it plugs into the serial port i see. this is the same as my MPI tuner plug in for my laptop, is there a splitter available so i can run both..
Also my laptop doesnt have a serial port in it, so i have a usb->serial adapter will that cause any problems??

That is part of the reason I bought the auto-tap. USB!paulmp3 said:
